Introduction:
Several studies reported that skeletal muscle mass affects the clinical response and quality of life of cancer patients during chemotherapy. Here we examined the adverse events and effects of anticancer drugs on the skeletal muscle mass of patients with esophageal cancer who received biweekly docetaxel, cisplatin, and 5-fluorouracil(DCF)neoadjuvant chemotherapy in our department.
Subjects And Methods:
We retrospectively analyzed 105 patients with esophageal cancer who received biweekly-DCF neoadjuvant chemotherapy in 2009-2019. The cross-sectional area of the psoas muscle at the level of the third lumbar vertebra on computed tomography was assessed to calculate the psoas muscle index(PMI). Patients were divided into the high PMI group(high-group)and low PMI group(low-group)by cut-off value(male: 6.36 cm2/m2; female: 3.92 cm2/m2). Hematological toxicity, non-hematological toxicity, and therapeutic effect were retrospectively examined.
Results:
Male in the high-group had significantly less ≥Grade 3 hematological toxicity than those in the low-group. Univariate and multivariate analyses showed that PMI(odds ratio: 1, p<0.05)was significantly related to decreased hematological toxicity.
Conclusion:
In preoperative chemotherapy for esophageal cancer, the incidence of hematological toxicity was significantly higher in patients with low skeletal muscle mass. Thus, skeletal muscle mass may be a marker for determining optimal anticancer drug dosage.
